The objective of this research is to determine the feasibility of using a biological system for templating particles into well-ordered two- and three-dimensional assemblies, with the vision toward new applications in nanoscale optoelectronic devices and high temperature electrochemical systems. The approach is to attach inorganic nanoparticles to protein templates to form highly-ordered two-dimensional arrays, characterize the spatial and optical properties of these protein-nanoparticle assemblies, and use layer-by-layer assembly to build three-dimensional protein-nanoparticle hybrid materials. Intellectual Merit:This research will develop a new strategy to construct nanostructured materials. The ability to fabricate assemblies comprising small inorganic nanoparticles into arrays of predetermined spacing and arrangement is currently not feasible. By enabling lattice parameter manipulation and ordered layer-by-layer assembly, arrays that consist of particles exhibiting the quantum size effect may reveal new properties. This, in turn, could enable the design of novel devices in areas such as optoelectronic technologies and fuel cells. Broader Impact:The program is necessarily a multidisciplinary endeavor, and it therefore represents an excellent opportunity for students to participate in a collaborative team effort and be trained to work with team members of diverse backgrounds. Under this proposed project, students at all educational levels (graduate, undergraduate, and high school) will be actively recruited. The results of this proposed work will also be integrated into topics presented in graduate-level courses.

本研究的目的是确定使用生物系统将颗粒模板化成有序的二维和三维组件的可行性，并展望在纳米级光电器件和高温电化学系统中的新应用。该方法是将无机纳米颗粒附着在蛋白质模板上形成高度有序的二维阵列，表征这些蛋白质-纳米颗粒组件的空间和光学特性，并使用逐层组装来构建三维蛋白质-纳米颗粒混合材料。智力优势：本研究将开发一种构建纳米结构材料的新策略。将小的无机纳米颗粒组装成预定间距和排列的阵列的能力目前是不可行的。通过使晶格参数操纵和有序的逐层组装成为可能，由表现出量子尺寸效应的粒子组成的阵列可能揭示出新的特性。这反过来又可以使光电技术和燃料电池等领域的新设备的设计成为可能。更广泛的影响：该项目必然是一个多学科的努力，因此它代表了一个极好的机会，让学生参与到一个合作的团队努力，并接受培训，与不同背景的团队成员一起工作。在这个拟议的项目下，将积极招募所有教育水平（研究生、本科生和高中）的学生。这项拟议工作的结果也将纳入研究生课程中提出的主题。
